说明
vnstatd is the daemon component of vnStat that collects network traffic statistics. It reads interface counters from the kernel at configured intervals and stores data in a persistent database. The daemon tracks multiple interfaces simultaneously, recording 5-minute, hourly, daily, monthly, and yearly statistics. It automatically detects new interfaces added to the database without requiring restart. Resource usage is minimal since vnstatd reads kernel counters rather than capturing packets. Data persists across reboots, making it suitable for long-term bandwidth monitoring.
